Title: Combustion turbines
Inventor: FRENCH MICHAEL JOSEPH
IPC: F01D3/04
Filed: 1954-04-26
Abstract: 763,993. Gas turbines; axial flow compressors. NAPIER & SON, Ltd., D. April 14, 1955 [April 26, 1954], No. 12067/54. Classes 110 (1) and 110 (3). In a gas turbine unit comprising an axial flow compressor, one or more combustion chambers, and an axial flow turbine driving the compressor, concentric rotary members respectively connected to the compressor and turbine rotors carry parts forming at least one piston and cylinder enclosing a chamber receiving air under pressure from the compressor, the arrangement being that the pressure acts on the parts in opposite axial directions to apply to the compressor and turbine rotors axial forces tending to counterbalance the axial loads on the rotors due to the reaction of the working fluid. The outer rotary member 12 is an extension of the turbine shaft 9, and has a splined connection, permitting axial movement, with a disc 14 fixed to the compressor shaft 5. The inner rotary member 21 has a ball and socket connection 20 with the compressor shaft, has a sliding connection with a tube 27 fixed to the turbine shaft, and is spaced from the outer rotary member by a ring 28. Discs 30 rigid with the inner rotary member act as pistons, and coact with discs 36 forming the cylinders and fixed to the member 12 to form high-pressure chambers 40 and low-pressure chambers 41. The high-pressure chambers receive air at pressure from the compressor by means of a passage 42, a conduit 43, and apertures 44. The low-pressure chambers are vented to an area of low pressure by ports 46, 47. The pressures on the discs 30, 36 tend to draw the compressor and turbine shafts together to counteract the reaction of the working fluid on the compressor and turbine rotors. A small quantity of the air flowing into the member 21 passes through the tube 27 through ports 45 to cool the turbine rotor discs 11. In a modification a piston and a cylinder are housed in a fairing downstream of the turbine, the inner rotary member extending through the turbine shaft to carry the piston, and the outer rotary member having an extension downstream of the turbine and carrying the cylinder. In a further modification a piston and cylinder are housed in a fairing upstream of the compressor.

A twisted tube 1 is built up of two mating portions 2 and 3, each having a uniform crosssection which is displaced radially at successive positions along the longitudinal axis of the tube. The portions 2 and 3 are metal troughs, made by pressing or casting in dies which may be similar for both parts and having flanges extending outwards from their longer edges. The flanges 5 and 6 of each mating pair are of unequal depth so as to provide a channel for solder or welding to form a pressure-tight joint. The tube is symmetrically ovoid in cross-section and each length is twisted uniformly through 22¢ degrees from end to end. Fig. 1 shows the minor axis of the ovoid in plan at its apparent narrowest part 8. Four such lengths are joined to form a twist of 90 degrees, their end edges being welded together over an internal sleeve which enters the ends at 9 and 10 of both lengths and has its lips expanded outwards at either end into an internal groove (Fig. 7, not shown), indicated in Fig. 1 by external ridges. The inside diameters of the sleeve are the same as those of the straight runs of piping to which the twists are normally joined at either end, but the internal diameters of the twist itself are slightly greater than this to prevent bodies passing through from sticking therein. In order that transistion may be smooth a short length of the tube 1 at 16 has the same internal diameters as the sleeve.
